VolumeScientific Papers of the Bureau of Standards, Vol. 16, 37-44 (1920) Scientific Paper 370 (S370)
Describes a new form of vibration galvanometer, which consists of a fine steel wire mounted on one pole of a permanent magnet, and so arranged that the free end may vibrate between the poles of an electromagnet through which the current to be detected passes. The sensitivity, though less than that of instruments of the moving-coil type, is higher than that of other moving-iron instruments, while it possesses the qualities of sturdiness, quick responsiveness, and freedom from the effects of external vibration.
